ABB NTU7UO Bailey INFI 90 Isolated Analog Output Termination Unit
The NTU7UO, also designated as NTU-7UO, is an isolated analog output termination unit designed for ABB Bailey INFI 90 distributed control systems (DCS). It serves as a dedicated interface between the control system output circuitry and external field devices, providing 14 isolated channels to manage analog control signals for valves, actuators, and variable-speed drives.
Termination and Signal Isolation
This unit facilitates structured field wiring while providing electrical isolation for its analog output channels. The isolation design helps mitigate electrical interference and ground loops during signal transmission to field instruments. It is engineered for installation within standard industrial control cabinets or system racks supporting ABB Bailey architecture.
